Spring @Service using JPA tuple queries for batch fetching invoice positions and cost assignments. fetchPositionen() bulk-loads positions for a list of invoices (both RechnungDO and EingangsrechnungDO) in a single query to avoid Hibernate lazy-loading N+1 problems. selectKostzuweisungen() fetches cost assignment data across invoices, resolving Kost1DO/Kost2DO via KostCache. Both methods use runIsolatedReadOnly for transactional isolation. SQL templates use Kotlin class simple names and parameterized IN clauses for batch efficiency.
